Tabs with Adaptive Cards

This App talks about the Teams tab which displays Adaptive card with CSharp.

This feature shown in this sample is in Public Developer Preview and is supported in desktop and mobile.

NOTE: Adaptive Card tabs will be deprecated in the new Microsoft Teams. Apps are expected to be available in the new Microsoft Teams by June 2023. If your app is using Adaptive Card tabs, it's recommended to rebuild the tab as a web-based tab. For more information, see Build tabs for Teams.

Included Features

  • Tabs
  • Adaptive Cards (in tabs)

Interaction with app

Adaptive Card

Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app manifest (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Tabs with Adaptive Cards: Manifest

Prerequisites

Run the app (Using Teams Toolkit for Visual Studio)

The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio.

  1. Install Visual Studio 2022 Version 17.10 Preview 4 or higher Visual Studio
  2. Install Teams Toolkit for Visual Studio Teams Toolkit extension
  3. In the debug dropdown menu of Visual Studio, select Dev Tunnels > Create A Tunnel (set authentication type to Public) or select an existing public dev tunnel.
  4. In the debug dropdown menu of Visual Studio, select default startup project > Microsoft Teams (browser)
  5. In Visual Studio, right-click your TeamsApp project and Select Teams Toolkit > Prepare Teams App Dependencies
  6. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps.
  7. Select Debug > Start Debugging or F5 to run the menu in Visual Studio.
  8. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

Setup

  1. Register a new application in the Microsoft Entra ID – App Registrations portal.
  • Select the Set link to generate the Application ID URI in the form of api://{base-url}/botid-{AppID}. Insert your fully qualified domain name (with a forward slash "/" appended to the end) between the double forward slashes and the GUID. The entire ID should have the form of: api://fully-qualified-domain-name/botid-{AppID} * ex: api://%ngrokDomain%.ngrok-free.app/botid-00000000-0000-0000-0000-000000000000.
  • Navigate to Authentication If an app hasn't been granted IT admin consent, users will have to provide consent the first time they use an app.
  • Set a redirect URI:
    • Select Add a platform.
    • Select web.
    • Enter the redirect URI for the app in the following format: https://{Base_Url}/auth-end. This will be the page where a successful implicit grant flow will redirect the user.
  • Set another redirect URI:
    • Select Add a platform.
    • Select web.
    • Enter the redirect URI https://token.botframework.com/.auth/web/redirect. This will be use for bot authenticaiton.
  1. Setup for Bot

  • Also, register a bot with Azure Bot Service, following the instructions here.

  • Ensure that you've enabled the Teams Channel

  • While registering the bot, use https://<your_tunnel_domain>/api/messages as the messaging endpoint.

    NOTE: When you create your app registration, you will create an App ID and App password - make sure you keep these for later.

  • In the Azure Portal, navigate back to the Azure Bot resource created (https://learn.microsoft.com/microsoftteams/platform/bots/how-to/authentication/add-authentication?tabs=dotnet%2Cdotnet-sample#azure-ad-v2) -Switch to the "Settings" blade and click "Add Setting" under the OAuth Connection Settings section

    • Enter a name for your new Connection setting.
      • In the Service Provider dropdown, select Azure Active Directory V2
      • Enter in the client id and client secret obtained in step 1 and 1
      • For the Token Exchange URL use the Application ID URL obtained in step 1
      • Specify "common" as the Tenant ID
      • Add all the scopes configured when specifying permissions to downstream APIs in step 1
      • Click "Save"
  1. Setup NGROK

  • Run ngrok - point to port 3978

    ngrok http 3978 --host-header="localhost:3978"

    Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

    devtunnel host -p 3978 --allow-anonymous
  1. Setup for code

  • Clone the repository

    git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

  • Modify the /appsettings.json and fill in the following details:

  • Run the bot from a terminal or from Visual Studio:

  • In a terminal, navigate to TabWithAdpativeCardFlow

    # change into project folder
cd # TabWithAdpativeCardFlow

  • Run the bot from a terminal or from Visual Studio, choose option A or B.

    A) From a terminal

    # run the bot
dotnet run

    B) Or from Visual Studio

    • Launch Visual Studio
    • File -> Open -> Project/Solution
    • Navigate to TabWithAdpativeCardFlow folder
    • Select TabWithAdpativeCardFlow.csproj file
    • Press F5 to run the project
  1. Setup Manifest for Teams

  • This step is specific to Teams.

    • Edit the manifest.json contained in the ./appPackage folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
    • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
    • Zip up the contents of the appPackage folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)

  • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

    • Go to Microsoft Teams. From the lower left corner, select Apps
    • From the lower left corner, choose Upload a custom App
    • Go to your project directory, the ./appPackage folder, select the zip folder, and choose Open.
    • Select Add in the pop-up dialog box. Your app is uploaded to Teams.

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.

Interacting with the tab in Teams

You can use this tab by following the below steps:
- In the navigation bar located at the far left in Teams, select the ellipses ●●● and choose your app from the list.
